Sound Meter

Free

Sound Meter is in the 4th set of the Smart Tools collection.Have you ever suffered from the noise of the neighbors?SPL(sound pressure level) meter app uses your built-in microphone to measure noise volume in decibels(db), and shows a reference. I had calibrated a lot of android devices with an actual sound level meter (dBA).
REMEMBER!! Most smartphone microphones were aligned to human voice (300-3400Hz, 40-60dB). Voice calls do not require high-performance microphones.Therefore the maximum value is LIMITED by manufacturers, and very loud sound(100+ dB) cannot be recognized. Moto G3 (max.80), Galaxy S6 (85dB), Nexus 5 (82dB), HTC Desire(82dB)...
See 6-7th images. I calibrated major android devices with an actual meter. You can trust the result in routine-noise levels (40-70dB). Please use it as an auxiliary tool.
